Even though dethroning the dollar from its current status as the primary reserve currency is not something that can happen in the current setup, there is discussion about what being a reserve currency means and what are the alternatives to a dollar reserve currency.
FT published an article on the subject and can be found here. It considers a few alternatives like (a) the renminbi, (b) the euro, (c) SDRs (Special Drawing Rights), (d) pegging to gold price. A lot of research has been done on these issues and some thoughts are presented in this article about the pros and cons of being a reserve currency or having one of the alternatives as reserve currency. Bellow are some passages taken from the article together with some of my own thoughts on the matters. The parts taken from the article are in quotation marks.
One reserve currency?
“In truth, the benefits to the US, in terms of support for its currency and its financial assets, are uncertain. Also unproved is the wider case that having just one reserve currency is inherently unstable, contributing to the global current account imbalances that are widening again as the world economy recovers from recession.”
Is one reserve currency an unstable structure because it leads to the currency’s devaluation according to the Triffin’s dilemma?
“On the face of it, a modern version of the Triffin critique explains recent persistent American current account deficits; they have been funded largely by foreign governments buying dollar bonds. But the causation is not straightforward. Under a floating exchange rate system, as long as countries accumulate only moderate amounts of currency reserves allowing them to intervene in any future crisis, the demand for dollar-denominated assets should be limited.”
Are SDRs a good alternative to one reserve currency?
“The SDR is closer to an accounting unit than a currency.”
“In order for the SDR to work as a proper global currency, Prof Eichengreen says, some organisation – probably the IMF – would need systematically to control its issuance beyond the current system of ad hoc one-off distributions. Any such proposal to globalise monetary policy would provoke explosions of disbelief in legislatures worldwide. As Prof Eichengreen concludes: “No global government, which means no global central bank, means no global currency. Full stop.”
Linking currencies to the price of gold?
“An even less likely option is linking currencies to the price of gold, recreating one of the models of international gold standard used in the past few centuries. Following the rapid rise of the gold price in recent years, a phenomenon some investors claim is driven by fears about fiat currencies (those not backed by a physical commodity) being debased by inflation, interest in the subject was revived last year by Robert Zoellick. The World Bank president raised the eyebrows of economic policymakers – before rushing to clarify that he was not in favour of a strict gold standard – by arguing that the metal had become an “alternative monetary asset” and that governments should consider using its price as an “international reference point of market expectations” for inflation and currency values.”
“However, economists have long argued that linking currencies and price levels to the value of a fixed or nearly fixed stock of precious metal means forcing real variables such as growth and employment to bear the brunt of economic shocks – a socially and politically unacceptable outcome. Prof Eichengreen, in response to Mr Zoellick’s speech, pointed out that targeting the domestic price of gold would have caused the Federal Reserve, the European Central Bank, the Bank of Japan and the Bank of England to have tightened monetary policy sharply in recent years. “It is lunacy to suggest that in circumstances of weak growth and deflation risk, key central banks should simultaneously tighten [policy],”
How about the Euro or the Renminbi?
For these two currencies to be used as reserve currencies they need to strengthen. By that is meant, to strengthen their institutions. For the Euro, Europe has to overcome its current debt crisis, and to emerge from it stronger. In this case Euro may gain some power as a reserve currency.
As far as the Renminbi is concerned, this is a more remote possibility. Perhaps in 30 or more years Renminbi could play a role as one of the reserve currencies. Until then, the Chinese institutions should have to strengthen and be accepted from the rest of the world. It is not just the size of the market that matters but also the stability of its institutions and the trust of the rest of world on them. This is by far the most important determinant of a currency in order to gain its reserve status.
